HELP For this problem, use x (cm), v(cm/s) and a(cm/s2).
a) What is the acceleration of the object?
b) Find the time needed for vxf = 0.
c) What is xf when vxf = 0? This is asking for xf using t in part b.
d) What is vxf when t = 2 sec?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
